Abstract
An image forming apparatus comprising: a laser beam irradiating device for irradiating a laser beam onto a record support member; a storage device for storing image data composed of a plurality of dots; a detection device which reads out the image data from the storage device so as to detect whether or not dots to be subjected to light emission by the laser beam are arranged continuously; and a control device for controlling an irradiation period of the laser beam irradiating device to a smaller value when the detection device has detected that the dots to be subjected to light emission are arranged continuously.
Claims8
An image forming apparatus comprising:
- a laser beam irradiating means for irradiating a laser beam onto a record support member;
- a storage means for storing image data composed of a plurality of dots;
- a detection means which reads out the image data from said storage means so as to detect whether or not dots to be subjected to light emission by the laser beam are arranged continuously;
- and
- a control means for controlling an irradiation period of said laser beam irradiating means corresponding to one dot to a second irradiation period of said later beam irradiating means when said detection means detects that the dots to be subjected to light emission are arranged continuously, the second irradiating period being shorter than the first irradiation period.
An image forming apparatus comprising:
- a laser beam irradiating means for irradiating a laser beam onto a record support member;
- a storage means for storing image dam composed of a plurality of dots;
- a delay circuit which outputs delayed image data obtained by imparting a delay of one dot to the image data read out from said storage means;
- a decision means for deciding whether dots to be subjected to light emission by the laser beam are arranged independently or continuously on the basis of the image data read out from said storage means and the delayed image data outputted from said delayed circuit;
- and
- a control means for controlling luminous intensity of said laser beam irradiating means in accordance with a decision of said decision means.
An image forming apparatus comprising:
- a laser beam irradiating means for irradiating a laser beam onto a photosensitive member;
- a storage means for storing image data;
- a judging means for judging whether or not a dot subjected to light emission by the laser beam is continuous with other dots in said storage means;
- and
- a control means for changing a first irradiation period of said laser beam irradiating means corresponding to one dot to a second irradiation period of said laser beam irradiating means smaller than the first irradiation period when said judging means judges that the dot is continuous with other dots.
